FIRE-PROOF WINDOW CASING AND FRAME.

SPECIFICATION forming part of Letters Patent No. 431,025, dated June 24, 1890.

Application filed January 24, 1890. Serial No. 338,035. (No model.)

To all whom it may concern.-

Be it known that I, EMIL EUGEN DAVOUST KERN, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have in vent-ed certain'new and useful Improvements in Fire-Proof Window Casings and Frames, of which the following is a specification.

My invention has for its object the construction of fire-proof casings and frames for windows and doors; and it consists of a casing of thin metal with a fire-proof non-conducting filling, of a frame or frames adapted to be mounted in such a casing, and likewise made of thin metal with a fire-proof filling, and of certain other features of construction and arrangement, which will be hereinafter pointed out.

In the drawings, Figure 1 is a perspective view of my invention applied to a windowcasing, part of the other shell of the casing being broken away. Fig. 2 is a detached view of the hinged parting-bead. Fig. 3 is a detached View of the inner swinging portion of the confining-rib. Figs. 4 and 5 are elevations, partly broken away, of the upper and lower-sashes, respectively. Fig. 6 is a section of the casing on the line 6 6 of Fig. 1, the upper sash being shown in section. Fig. 7 is a section on the line 7 7 of Fig. 1, looking in the direction of the arrow. Fig. 8 is a section of the casing on the line 8 8 of Fig. l.

The casing, which is represented generally by the letter A, is adapted to be set into an opening in the wall, either external or internal, of a building, and may be used as a support for a door or a window, preferably for the latter. It conists of thin metal either in sheets or plates 9 h, properly shaped and united so as to be separated from each other to form a space adapted to receive anon-conducting packing material B, such as asbestos or mineral wool. The inner plates or sheets of metal g are corrugated to form seats, in which may rest the frame or frames supported by the casing. Thus, as shown in the drawings, the inner plates of the sides and upper portion of the casing are shaped so as to form two grooves 2' j, in which work the two sliding sashes O and D, respectively. These grooves are formed by corrugating the plates 9 to form the parting rib or bead is between the grooves i and j, and the confining ribs or raised portions ZZon the outer sides of the grooves. The opposing outer plate 7?, preferably lies parallel with the plate g throughout the greater portion of its length, so that there are formed recesses or grooves mm on the outside of the casing, which at the sides serve in part as the channels in which the sashweights may move. Between the grooves m the plates or sheets h are by preference plane. The lower portion of the casing is not provided with an outside raised portion or confining-rib Z, but extends as a flat surface outward from the inner confining-rib Z, forming a fiat sill n, as shown in Fig. 7.

The parts of the casing are united to each other in any suitable manner, preferably by folding and riveting, as itis desired to dispense with the use of screws and bolts and to avoid allsoldering.

The construction of the glass holding frames or sashes will be understood from an examination of Figs. 4, 5, 6, and 7. Each stile and rail of this frame is hollow, so as to receive a packing p of suitable material, and is formed of a single piece of metal shaped to have the ribs 0, against which the panes of glass are set. The glass is held in place by tabs or spurs e, which are integral with the sash-frame, and are formed by cutting the metal so that they may be bent to permit the glass to be put in place, and then bent to confine the glass against the ribs'o. The stiles and rails are united at the corners of the frame by rivets, as at r, Fig. 4.

In order that the upper and lower sash frames may be easily inserted into and re moved from the grooves in which they move, I remove a portion of the parting rib orbead it between the grooves, and of the inner confining strip or rib Z opposite one of the grooves, these removed sections being of alength substantially that of the-sash which it is desired should be removed, and the lines on which they are cut or separated from the casing being substantially coincident with the bottoms of the grooves, and I replace such removed portion by movable rib-sections, which are preferably hinged to the casing. As shown in Figs. 1 and 2, the lower portion of one of the parting ribs or beads is removed, and a section I) is there hinged so that it may be swung upward, and thus permit the outer sash to be removed inward. A portion of the inner confining-rib Z, opposite the movable rib-section b of the parting bead, is also removed and replaced by a rib-section c, hinged to the casing,

preferably by one of its edges, so that it may swing inward out of the way of the sash. The form of hinge I prefer for the rib-section c is that shown at q in Fig. 3, which extends along one edge of the section from end to end. This form of hinge I prefer because it makes a more neat connection with the easing and because it better covers the joint between the sections 0 and the casing, thereby the more effectually preventing drafts of air. These movable portions 1) and c are of metal and hollow, and may receive a suitable fireproof packing material. They are each provided with suitable means for looking or con fining them in place, such as the slidingbolts 2? shown in the drawings.

The edges of the casing may terminate as shown in Figs. 6, 7, and 8, or otherwise. Thus the inner edge of the sill part of the casing could be made longer and bent downward to form a molding or other ornamental finish for the casing.

Among the advantages incident to my invention are ease of construction, proof against destruction by fire, and lightness in weight. By making the sash-frames as described it is not necessary to screw or solder together the partswhich is obj ectionablein order to permit the removal and insertion of the glass; but this may be done by simply bending the tabs orspurs c. It will of course be nnderstood that putty or similar material is used to hold the glass in place in addition to the tabs or spurs 6.

Without limiting myself to the precise con struction and arrangement of the parts shown, what I claim is 1. A hollow casing for windows formed of thin metal shaped to form the outer grooves m m, the inner grooves for the sash-frames, and the ribs 70 Z Z, the casing being packed with a fire-proof non conducting material, substantially as described.

2. A metal casing for windows and the like,

moved from the grooves in which they move,

substantially as described.

3. A hollow casing for windows formed of thin metal bent toform the outer grooves m m, and the inner grooves 71 j for the sashframes, and the ribs R Z Z,substantially as described.

4. A metal casing for a window made with the integral corrugations or ribs which form the sash-grooves, the said corrugations or ribs being cut away or removed sufficiently to permit the withdrawal of the sash-frames,

and the rib-section b, hinged at its end, and

the rib section 0, hinged along its edge, the said rib-sections being adapted to fill the cutaway portions of the said corrugations or ribs, or to be swung on their hinges away therefrom, substantially as described.

5. Ametal sash-frame having a rib' against which the glass may be set and tabs or spurs integral with the metal from which the frame is formed and adapted to hold the glass against the said rib, substantially as described.

6. A metal fire-proof sash made hollow and packed or filled with a fireproof material, and having arib against which the glass may be set, and tabs or spurs integral with the sash and adapted to hold the glass against the said rib, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
